Introduction and System Requirements: Host computers that run Workstation Pro must meet specific hardware and software requirements. Virtual machines that run in Workstation Pro support specific devices and provide certain features. This chapter includes the following topics: - Host System Requirements for Workstation Pro - Virtual Machine Features and Specifications

VMware vSphere® is a virtualization platform that forms the foundation for building and managing an organization's virtual, public, and private cloud infrastructures. VMware vCenter® Server Appliance™ (vCSA) sits at the heart of vSphere and provides services to manage various components of a virtual infrastructure like ESXi hosts, virtual machines, and storage and networking resources. As large virtual infrastructures are built using vSphere, vCenter Server becomes an important element in ensuring the business continuity of an organization. vCenter Server must protect itself from a set of hardware and software failures in an environment and must recover transparently from such failures. vSphere 6.5 provides a high availability solution for vCenter Server, known as vCenter Server High Availability, or VCHA. This paper shows: • VCHA performance characterization: A preliminary performance evaluation of the VCHA feature. • VCHA best practices: Some guidelines for VCHA deployment and configuration.

The realm of technology is one that has traditionally been constructed on silos. We tend to fragment our skills into very specific areas of expertise, even going so far as to isolate the very people who run data center and cloud operations into little buckets of focus and energy. I’d like to think that this, more than anything, was the root cause for such painfully slow progress towards realizing the dream of a fully software defined data center. I had always felt a bit stifled by this organizational fragmentation and thirsted for a way to put my hands on just about any solution that shows the promise of removing the burden of manual processes. Since you’re reading this book, I’ll make the assumption that you have had similar thoughts.

It’s hard to believe how far we’ve come in the virtualization industry. What was once considered a niche technology used only for development and testing is now used for production work- loads and even business-critical applications. The VMware vSphere platform is capable of sup- porting nearly any virtualized workload with very few obstacles standing in the way of close to 100 percent virtualization. Today’s workloads are more demanding than ever before. Email servers frequently require large amounts of memory and CPU resources in order to handle the large volume of email that we all deal with on a daily basis. Database servers often require large amounts of memory and storage resources, from a capacity perspective as well as performance, to meet the demands of a business. And newer technologies, such as virtual desktop infrastructure (VDI), have intro- duced signii cant demand for resources in vSphere environments.
